This project aims to analyze user sentiments and categorize them as Postive, Negative, or Neutral.¶

Explanation: Nowadays, customer feedback plays a substantial role in shaping buying choices within the market. For instance, Google gives preference to websites that receive favorable reviews from their users. Consequently, it becomes essential to identify and address negative reviews to prevent them from potentially harming product marketing efforts.

Inference -¶

The more the size of word, the more frquently that appear in the reviews.¶
We can see that both good and headphon are the two words which are big in size. So it we can say, that many people have given review that headphones are good.¶
